I connect my android phone to the Pi using USB and turn on the tethering. Everything runs smooth, I can
ssh to the Pi using the phone and it's address (usb0 - 192.168.42.xxx). After, that I connect the Pi to my WiFi network and test the
ssh connection again (wlan0 - 192.168.88.xxx), and again everything runs smooth.
The problem is that I can't port forward it when it is connected using the USB. When I tried to connect from a different network, it just timed me out. So, I unplugged the USB cable and after that I can
ssh to the Pi. How can I make it run on all the addresses (usb0 (phone network), wlan0 (WiFi network) and the port forwarded WiFi (my IP address))?
